Entwined, the game released for PlayStation 4 during Sony's E3 presentation, will be expanding to more platforms soon.
That's according to Pixelopus creative director Dominic Robilliard, who mentioned on the PlayStation Blog that the PS3 and Vita versions would be coming "in the very near future." He said the team is wrapping up those versions this week, so presumably it would hit both platforms after passing through certification from Sony.
As originally announced, the PS3 and Vita versions will be cross-buy, so if you've already gotten it on PlayStation 4 you should be set for the other two. It's available for $9.99 on the PlayStation Network.
